A communication system covering an area, including a plurality of first units. Each of the first units being configured to control the allocation of channels in a part of the area. At least one of the first units being configured to send information relating to channel allocation in the part of the area associated with the at least one first unit to at least one other of the first units. The at least one other of the first means units being configured to take into account the received information when controlling the allocation of channels in the part of the area associated with the at least one other first units.

Channel allocation for communication system

A communication system, said system arranged to provide communication coverage over an area, said system comprising a plurality of first means, each of said first means controlling at least one parameter and/or configuration setting with respect to an area smaller than said coverage area and second means for receiving information from a plurality of said plurality of first means and for controlling at least one parameter and/or configuration setting with respect to the area associated with at least one of said plurality of said plurality of first means.

Communication system

A method in a communication network comprising a core network and a radio access network. At least one target cell is defined for at least one originating cell controlled by a first radio access network node. A request for a packet switched communication address of a second RAN node of the target cell is delivered to the second RAN node, and a response comprising the requested address is returned. The request and the response are transferred between the first radio access network node and the second radio access network node in information containers that are transparent to the core network. The received address information is stored in the first radio access network node for facilitating delivery of data packets between the originating cell and the target cell. Based on the stored cell-specific information, information may be exchanged between the nodes controlling the cells without congesting the essential core network elements and interfaces.

Management of cell-specific address information

The invention relates to a method of allocating Abis interface transmission channels in a packet cellular radio network, and to a network part utilizing the method. The method comprises () allocating fixedly a certain number of transmission channels to base-station-specific operations and maintenance signalling and to transceiver-specific telecommunication signalling; and () allocating dynamically, using in-band signalling, a necessary number of transmission channels to packet data transfer, the amount of packet data varying according to the modulation and coding scheme used on a Um interface.

Allocating Abis interface transmission channels in packet cellular radio network

A method for use in a network covering a region, said region comprising a plurality of areas, a user being assigned to at least oen of said area and having associated therewith a plurality of candidate areas to which the user may be assigned, said method comprising the steps of receiving information identifying said plurality of candidate areas; estimating for each candidate area a parameter, said parameter assuming that said user is assigned to said candidate area; and prioritising said plurality of candidate areas which takes into account the estimated value of said parameter.

Radio resource management

A method and an apparatus implementing the method for optimizing data transmission resources, particularly resources on the air interface, between terminals and a network element. To diminish capacity differences of different legs or connection parts in the connection, the network adapts (--A,-) the traffic channel resources between the terminal and the network to be suitable for the outward connection of the network element, e.g. the connection to another mobile station or to a fixed network, by observing and comparing the data transmission capacities of the connection parts or by receiving from the outward connection part the information (--A,-B,--) on its data transmission capacity.
